Selection of SMD resistance accuracy:

The higher the precision of resistance, the higher the price is an indisputable fact, but how to balance the cost and design requirements is a very learned thing, has not only the design ability of the problem. The main considerations are as follows:

1. Maintainability and maintenance cost

2. Use environment and product type

3. Signal requirements and allowable error range

4. Cost and performance

5. The impact of production cost and process

6. Other factors
